Two 3080 mines a day
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing
21.5 * 3600 seconds * 24 hours = 1857600 M / day
1857600 / 1024 / 1024 = 1.7715 T / day
a t of computing power / day can dig bitcoin worth 4.03 yuan
1.7715 * 4.03 = 7.14 yuan / day
since 2017, bitcoin has reached new heights. Yesterday (May 23), the value of bitcoin broke through the ￥ 16000 mark, hyping virtual currency, becoming a matter that the general public can participate in, And a little bit of technical level, both fried money, but also began to have the technical content of mining
as we all know, virtual currency has a numerical peak, the more difficult it is to dig. In fact, it's hard to judge whether to lose money or not if we continue to dig. Therefore, in the end how to dig, dig what can be the fastest back to this, this paper studies the above two core issues based on the current market situation
Every 100 S4 bitcoin mining machines consume 900W of electricity per hour
Taking t2t-30t as an example, the calculation force of t2t-30t is 30t, and the power consumption is 2200W, that is, 2.2kW. The power consumption of a single miner in 24-hour operation is 2.2kW * 24 = 52.8kwh, and the electricity charge is once calculated as 0.56rmb, the daily power consumption cost of a single miner is 52.8kw * 0.56 = 29.57rmb
to "mine" with bitcoin mining machine, if the graphics card is fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. There are many professional mines at home and abroad in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even some people in a residential area in Yunnan carried out crazy mining, which led to a large area trip of the residential area, and the transformer was burned

mining principle of bitcoin mining machine:
bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through point-to-point network, digital signature and interactive proof system. Each network node carries out broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain
every node of bitcoin will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the sha256 hash value of the previous data block. The mining node keeps trying again and again until the random adjustment number it finds makes the hash value lower than a specific target
According to the current computing power of the whole network, it takes 54436.5t of computing power to dig a bitcoin 24 hours, that is, one bitcoin a day< it requires 746 mining machines with the latest 73t capacity on the market to work together for 24 hours
the cost of mining mainly includes (mining machine cost / power cost). Now the latest miner is 22650 yuan, a miner consumes 77 kwh per day. At present, the price of mining machinery on the market is about 0.36 yuan, 28 yuan per day. The cost of mining bitcoin = mining machine price (22650)
mining bitcoin requires a professional site "mine" to place mining machines. The construction cost of placing about 3000 mining machines in a small professional mine is about 300 watts

unable to mine at home
the noise of 60-80 decibels will be proced by the mining machine in the working process. Mining at home is not feasible, the miner needs 24 hours of endless operation, so the temperature of the miner will be very high, the maximum temperature can reach 80 degrees. Therefore, mining needs a good environment to rece the temperature. Household electricity and electricity charges are high, and the cost is higher than the income. In addition, mining has a certain degree of professionalism, professionals need to carry out certain operation and maintenance to ensure the normal operation of the mining machine
the key to rece the mining cost is to purchase mining machines in batches and low electricity charges. Professional mine is built to ensure the operation of mining machinery. At present, the mainstream mining machinery manufacturers are bitcontinental Technology Co., Ltd. in Beijing and Jianan Yun Technology Co., Ltd. in Hangzhou. Mining machinery is proced in the form of appointment in futures. It is difficult for indivials to buy Mining machinery in small quantities on the official website. After years of development, the mining machinery market has formed a complete instrial chain. The price of mining machinery fluctuates with the price of money, and the power resources are basically distributed in the cheap western region. Getting cheap electricity prices requires personal resource advantages

bus line: No.13, the whole journey is about 6.4km
1. Walk 820 meters from Hedong, Suining Central Hospital, to the East Coast Community station
2. Take No.13, pass 8 stations, and reach the railway station
3. Walk 390 meters to Suining railway station
Is the clone version of the system can not be installed, install the original Microsoft win10 certainly no problem. The method is as follows
win10 startup disk proction and installation
startup disk proction:
prepare a U disk, which is divided into only one partition
format the U disk, and use FAT32 as the file format.
download the original win10 system of Microsoft and unzip it
all about 10 extracted files are copied to the U disk root directory. The startup disk is finished<
win10 installation:
insert the USB flash disk into the computer to install the system
press the start shortcut key to select USB flash disk to start, and the installation will be automatic. When the disk is selected, select C disk and format c disk. Follow the prompts to complete the installation
with startup shortcut key
the simplest and most economical route is:
take Metro Line 2 (15 stops) from entrance h of Guangzhou south railway station to Metro Guangzhou station, transfer to Metro Line 5 (18 stops) and get off at entrance D of Wenchong station, then go to Wenchong market station, transfer to No. 943 (16 stops) and get off at North Gate Station of performance center. Walk about 640 meters to Guangzhou International Sports Performing Arts Center. A little bit of twists and turns, and a little bit of pocket
take a taxi: 42.5km, about 134 yuan
the pure bus line is:
take bus No.303 a from the bus terminus of Guangzhou South Railway Station (take 24 stops) to Yantang Enterprise Station 1, go ahead to Yantang Enterprise Station 2, and then transfer to peak express 64 (take 20 stops) to the South Gate Station of the performing arts center. Cross the road and go right about 210 meters to Guangzhou International Sports Performing Arts Center
it should be fast and simple to transfer from subway to bus! Pure bus line, transfer, waiting for a bus, taking a bus are a little time-consuming! Renting is the most convenient, the fastest and the most expensive!
